FIELD-ROLLER.

SPECIFICATION forming part of Letters Patent No. 503,629, dated August 22, 1893. Application filed March 22,1 99. Serial r... 467,176. (No man.)

To all whom it may concern.-

EBe it known that I, JOHN S. WECKMAN, of

Ganton,in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Field-Rollers, of which the following is a specification.

This invention consists in certain improvements upon the field roller described in Lettors-Patent of the United States No. 387,468, granted to me August 7, 1888. In said patent there is described a single roller having its periphery composed of round separated longitudinal crushing pipes. In accordance with the present invention there are three rollers, a forward or leading roller, and two trailing rollers located side by side and at the rear of the leading roller. The reach which connects the trailing rollers with the leading roller is pivoted at its forward end to the frame of the leading roller so that the leading roller may turn horizontally, and the frames of the trailing rollers are pivotally connected with the reach so as to turn vertically, whereby the entire machine may turn around easily, and the trailing rollers may I rise and fall to accommodate themselves to States Letters-Patent No. 167,380, granted September 7, 1875, to Ephraim H. Adams, and in United States Letters-Patent No. 199,508, granted January 22, 1878, to Roger W. Bunt- 1n The present improvements in respect to the general arrangement consist in the improved means for connecting the parts together.

The principal part of the present invention relates to the construction of each of the cylinders or rollers. Instead of the periphery of each roller being composed of separated pipes, it is composed of semi-tubular or semicylindrical concave-convex crushing bars extending longitudinally. Preferably in connection with these semi-cylindrical concavoconvex crushing bars, specially-shaped heads are employed to receive them. Each cylinder or roller also has,by preference, a strength ening wheel at its center to support the crushing bars at their centers.

The present improvements are illustrated in the accompanying drawings, wherein-= Figure 1, is a front View of a single roller or cylinder detached from the machine and constructed in accordance with the present improvements. Fig. 2, is an end view of the cylinder or roller. Fig. 3, is a perspective view of one end of one of the semi-cylindrical concavo-convex crushing pipes. Fig. 4, is a perspective view of a portion of one of the roller heads. Fig. 5,isacross-section through a portion of the crushing bars looking toward the inner face of one of the roller heads. Fig. 6, is a cross-section through a portion of the crushing bars looking toward the central strengthening wheel of one of the rollers. Fig. 7, is a view similar to Fig. 5, showing a modification of the roller head. Fig. 8, is a longitudinal section through one of the crushing bars, both roller heads and the central strengthening wheel, illustrating the modification shown in Fig. 7. Fig. 9, is a perspective view of the entire machine. Fig. 10, is a detail' sectional View showing the pivotal connections between the frame of the leading roller and the reach. Fig. l1,is adetail view of the pivotal connection between the reach and the frame of one of the trailing rollers.

I will first describe the construction of one of the rollers, as illustrated in Figs. 1 to 6 inclusive. The roller is composed of two heads A, B, a central strengthening wheel 0, and a plurality of longitudinally-extending crushing bars D D, which extend between heads AB and are supported at their centers by the wheel 0. The several bars D D constitute a cylinder, with longitudinal spaces between them, so that the roller is an open roller as in my said Patent No. 387,468. Each of the crushing bars D is semi-tubular or semi-cylindrical and concavo-convex in cross section,

as shown in Figs. 3, 5, and 6. The crushing bars are so mounted on the heads that their convex portions are on the outside, so that is that the roller can be used to roll gfbinid same.

lighter, taking only one-half the metal, and f be. rolled 1 are much cheaper since they can out from steel.

To receive the semi-cylindrical crushing bars D, each of the heads A B is specially f0rmed,"as' is snowsmos-tcl'arly in Fig; Each head is made of a single pi'ece'of metal;

and has a circular rim or tread a connected by radial spokes b b, with a central hub c (see Fig} 2) through wlii'ch p'as'ses the aile P; an outer flange d perpendicular to the rim dgzfifid a plu ality of lugs e'e'oh foreach or tlibars D. Each lug e is shaped to fit withinth'e corica'v'e rate of its crush ng bar, and is or adepth somewhat less than that of the an-gt d, as seen at f; The several erus'hingbar's fit over the lugs eaidapqt against the flafigedwhieh insures their proper position. Each l'ugilias' a bolt-hole g'and each bar has abolthole; 12,, through which passes a fastening bolti, "ch is secured in place by a nut j on the'insrdeqf the mind; as shown most clearly 111' Fig; 5.
